摘　　要：针对YW220型液压挖掘机的工作装置复杂的受载状态,基于虚拟样机技术对其危险工况进行了分析,并同传统设计方法使用的危险工况进行了比较,验证了其准确性.对挖掘装置部件使用UG软件建立虚拟样机模型,并对模型进行了参数化处理;采用ADAMS软件仿真模型的运动约束,利用设计变量驱动模型,实现了全工作域内的运动,并进行了动力学分析;同传统设计方法使用的危险工况进行了比较,验证了采用参数化方法在确定危险工况方面的准确性.结果表明:采用DOE(Design of Experiments)分析技术能精确判断出挖掘装置在挖掘过程中的最危险位置,在确定危险工况方面较传统设计方法更加准确,进一步验证了机构的可靠性.The load-up condition on excavating gear of YW220 hydraulic excavator is complicated.Based on virtual prototype,the dangerous working condition was analyzed,and compared with traditional design method.The simulation model of excavating gear was built with UG software in parameterizes.The ADAMS software was used to simulating model movement.The design variable was used to drive model to realize motion on whole working region.The result of parameter method kinetic analysis on excavating gear was compared to traditional method result on dangerous operating mode.The results illustrate that DOE analysis techniques can accurately determine the mining device in the most dangerous position in the mining process and parameter method is more precise than tradition procedure.It tests that the structure is more reliability.
